Detailed Description
Features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is in no way limited to any specific configuration and algorithm set forth below, but rather covers any modification, replacement or improvement of elements, components or algorithms without departing from the spirit of the invention. In the drawings and the following description, well-known structures and techniques are not shown in order to avoid unnecessarily obscuring the present invention.
An embodiment of the invention provides a pixel arrangement structure, a Display panel and a Display device, which can be applied to various Organic Light-Emitting Diode (OLED) Display devices, Light-Emitting Diode (LED) Display devices, Liquid Crystal Display (LCD) devices, and the like, such as smart watches, computers, mobile phones, tablet computers, and the like, without limitation. The pixel arrangement structure in the embodiment of the invention is adopted to arrange the pixels, so that fewer sub-pixels can be effectively utilized, more pixels can be obtained, and the pixel density of the display panel can be improved.
The pixel arrangement structure in the embodiment of the invention comprises a plurality of repeated units which are repeatedly arranged. Each of the repeating units includes a first sub-pixel, a second sub-pixel, and a third sub-pixel.
Wherein, a compensation pixel is arranged in every N repeating units. Each repeating unit may serve as one pixel. The compensation pixel is composed of a part of sub-pixels in one of the N repeating units and a part of sub-pixels in another repeating unit adjacent to the one repeating unit. Each compensation pixel includes a first sub-pixel, a second sub-pixel, and a third sub-pixel. For example, in two adjacent repeating units, the third sub-pixel in the first repeating unit and the first sub-pixel and the second sub-pixel in the second repeating unit form a compensation pixel.
In order to ensure that the granularity degree is low when the display panel with the pixel arrangement structure in the embodiment of the invention is used for displaying, N is a positive integer larger than 2.
The following description will be given by taking N as 3 as an example. Fig. 1 is a schematic diagram of a pixel arrangement structure according to an embodiment of the present invention (only a part of the pixel arrangement structure is shown). The sparse dashed frame is the repeating unit 10, and the dense dashed frame is the compensation pixel 11. As shown in fig. 1, one compensation pixel 11 is disposed in the first three repeating units 10 in the first and second rows. The compensation pixel 11 is composed of a third sub-pixel 103 in the first repeating unit 10 in the first and second rows and a first sub-pixel 101 and a second sub-pixel 102 in the second repeating unit 10 in the first and second rows. One compensation pixel 11 is provided in the fourth to sixth repeating units 10 in the first and second rows. The compensation pixel 11 is composed of a third sub-pixel 103 in the fourth repeating unit 10 in the first and second rows and a first sub-pixel 101 and a second sub-pixel 102 in the fifth repeating unit 10 in the first and second rows. Each repeating unit 10 may act as a pixel, in this example, every 3 repeating units 10 may achieve a display effect of 4 pixels. As shown in fig. 1, the arrangement of the compensation pixels 11 in the third to sixth rows is similar to the arrangement of the compensation pixels 11 in the first and second rows, and thus, the description thereof is omitted.
Fig. 1 shows only a part of the pixels arranged in the pixel arrangement structure in the display panel. On the basis of fig. 1, a plurality of repeating units 10 may also exist extending to the periphery, and the compensation pixels 11 disposed in the repeating units 10 may refer to the compensation pixels 11 in fig. 1, and are not described herein again.
In the embodiment of the present invention, in a plurality of repeating units 10 arranged repeatedly, in every N repeating units 10, one compensation pixel 11 is configured by using a part of sub-pixels in one repeating unit 10 and a part of sub-pixels in a repeating unit 10 adjacent to the one repeating unit 10, so that a display effect of N +1 pixels can be achieved every N repeating units 10. Thereby, in the display panel of the same size, the pixel density can be increased. In addition, when N is a positive integer greater than 2, the graininess of an image displayed on the display panel can be reduced, and the display effect of the display panel can be improved.
In order to ensure that the pixel density of the display panel including the pixels arranged according to the pixel arrangement structure in the embodiment of the present invention can be high, N in the above embodiment may be set to be a positive integer less than 6, for example, N may be 4 or 5.
For example, fig. 2 is a schematic diagram of another pixel arrangement structure in the embodiment of the present invention (only a part of the pixel arrangement structure is shown). The sparse dashed box is the repeating unit 10, and the dense dashed box is the compensation pixel 11. As shown in fig. 2, N is 4. That is, one compensation pixel 11 is provided in every 4 repeating units 10. One compensation pixel 11 is disposed in the first to fourth repeating units 10 in the first and second rows. One compensation pixel 11 is disposed in the first to fourth repeating units 10 in the third and fourth rows. One compensation pixel 11 is disposed in the first to fourth repeating units 10 in the fifth and sixth rows.
Furthermore, the position of the compensation pixel 11 in the N repeating units 10 may also be different in the different N repeating units 10. For example, as shown in fig. 2, the compensation pixels 11 in the first and second rows are composed of the third sub-pixels 103 in the first repeating unit 10 in the first and second rows (i.e. the third sub-pixels 103 in the second columns of the first and second rows), and the first sub-pixels 101 and the second sub-pixels 102 in the second repeating unit 10 in the first and second rows (i.e. the first sub-pixels 101 in the third columns of the first row and the second sub-pixels 102 in the third columns of the second row). The compensation pixel 11 in the third and fourth rows is composed of the first sub-pixel 101 and the second sub-pixel 102 in the second repeating unit 10 in the third and fourth rows (i.e. the first sub-pixel 101 in the third row and the fourth column and the second sub-pixel 102 in the fourth row and the fourth column), and the third sub-pixel 103 in the third repeating unit 10 in the third row and the fourth row (i.e. the third sub-pixel 103 in the fifth column in the third row and the fourth row). The compensation pixels 11 in the fifth and sixth rows are composed of the third sub-pixel 103 in the third repeating unit 10 in the fifth and sixth rows (i.e., the third sub-pixel 103 in the sixth column of the fifth and sixth rows), and the first sub-pixel 101 and the second sub-pixel 102 in the fourth repeating unit 10 in the fifth and sixth rows (i.e., the first sub-pixel 101 in the seventh column of the fifth row and the second sub-pixel 102 in the seventh column of the sixth row).
In some examples, the first subpixel 101 and the second subpixel 102 may be arranged in one column and the third subpixel 103 may be arranged in another column in each of the repeating units 10. One column is adjacent to another column, but the specific positions of the adjacent column and the other column are not limited.
For example, as shown in fig. 1 and 2, the sub-pixels in each repeating unit 10 have a side-inverted delta shape. As shown in the first repeating unit 10 in the first row and the second row of fig. 1, the first sub-pixel 101 and the second sub-pixel 102 are located in the first column, and the third sub-pixel 103 is located in the second column. Also as in the first repeating unit 10 in the third and fourth rows of fig. 2, the third sub-pixel 103 is located in the first column and the first sub-pixel 101 and the second sub-pixel 102 are located in the second column.
Also, in the same pixel arrangement structure, the arrangement of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 in the repeating unit 10 located in different rows may be slightly different. For example, as shown in fig. 2, in the repeating unit 10 of the first row and the second row, a column in which the first sub-pixel 101 and the second sub-pixel 102 are located is a column previous to a column in which the third sub-pixel 103 is located. In the repeating unit 10 in the third row and the fourth row, the column in which the first subpixel 101 and the second subpixel 102 are located is a column subsequent to the column in which the third subpixel 103 is located. The arrangement of the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 in the repeating unit 10 in different rows is different, so that the light emission of the display panel is more uniform, and the display effect of the display panel can be improved.
In some examples, the plurality of compensation pixels 11 are randomly distributed in the pixel arrangement structure, and a specific position of the plurality of compensation pixels 11 in the pixel arrangement is not defined.
In other examples, the plurality of compensation pixels 11 are uniformly distributed in the pixel arrangement structure. The display compensation effect of the compensation pixels 11 distributed uniformly on the whole display panel is also uniform, so that the display effect of the display panel is further improved.
For example, fig. 3 is a schematic diagram of another pixel arrangement structure in an embodiment of the invention (only a part of the pixel arrangement structure is shown). The relatively sparse dashed frame is the repeating unit 10, and the fine dashed frame is the compensation pixel 11. As shown in fig. 3, the compensation pixels 11 are not distributed in a column, but are distributed in a staggered manner. In particular, the first compensation pixels 11 in the first and second rows occupy the second and third columns. The first compensation pixels 11 in the third and fourth rows occupy the fourth and fifth columns. The first compensation pixels 11 in the fifth and sixth rows occupy the second and third columns.
The compensation pixels 11 are distributed in a staggered manner, so that the display compensation effect brought by the compensation pixels 11 can be prevented from being highlighted on a straight line in the vertical direction of the display panel, and the display effect of the display panel is further improved.
In still other examples, the plurality of compensation pixels 11 are arranged along at least one oblique line in the pixel arrangement structure, and the oblique line forms an oblique angle with a frame of the pixel arrangement structure.
For example, fig. 4 is a schematic diagram of another pixel arrangement structure according to an embodiment of the present invention (only a part of the pixel arrangement structure is shown). The sparse dashed box is the repeating unit 10, and the dense dashed box is the compensation pixel 11. As shown in fig. 4, the five compensation pixels 11 in fig. 4 are arranged along two oblique lines, and both the two oblique lines form oblique angles with the frame of the pixel arrangement structure shown in fig. 4. The frame of the pixel arrangement structure may be formed by a straight line on which the outer sides of the outermost circles of sub-pixels are located. Specifically, the first compensation pixels 11 in the first and second rows, the first compensation pixels 11 in the third and fourth rows, and the first compensation pixels 11 in the fifth and sixth rows are arranged along an oblique line. That is, the bottom right corner endpoint of the first compensation pixel 11 in the first and second rows and the top left corner endpoint of the first compensation pixel 11 in the third and fourth rows are adjacent, and the bottom right corner endpoint of the first compensation pixel 11 in the third and fourth rows and the top left corner endpoint of the first compensation pixel 11 in the fifth and sixth rows are adjacent. The second compensation pixels 11 in the first and second rows, and the second compensation pixels 11 in the third and fourth rows are arranged along another oblique line. That is, the lower right corner endpoint of the second compensation pixel 11 in the first and second rows and the upper left corner endpoint of the second compensation pixel 11 in the third and fourth rows are adjacent. In the pixel arrangement structure shown in fig. 4, two oblique lines along which the compensation pixels 11 are arranged are parallel.
The compensation pixels 11 in the pixel arrangement structure are arranged according to at least one oblique line, so that the compensation pixels 11 are uniformly distributed in the whole display panel, and on the basis of improving the pixel density, the light emission of the display panel is more uniform, and the display effect of the display panel is further improved.
In some examples, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 in the above embodiments may be configured to emit light of different colors. Specifically, the first subpixel 101, the second subpixel 102, and the third subpixel 103 may be configured to emit red light, green light, and blue light, respectively. Of course, the first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 may be configured to emit light of different colors in other combinations. For example, the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 may be configured to emit red light, blue light, and green light, respectively. Or the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 may be configured to emit blue light, red light, and green light, respectively. The first sub-pixel 101, the second sub-pixel 102 and the third sub-pixel 103 are configured to emit light of different colors and are not limited herein.
In the embodiment of the present invention, the length of the third sub-pixel 103 in the vertical direction in each repeating unit 10 may be longer than, equal to, or shorter than the length of the region occupied by the first sub-pixel 101 and the second sub-pixel 102 in the repeating unit 10 in the vertical direction. In the pixel arrangement structure shown in fig. 1 to 4, the length of the third sub-pixel 103 in each repeating unit 10 in the vertical direction is equal to the length of the region occupied by the first sub-pixel 101 and the second sub-pixel 102 in the repeating unit 10 in the vertical direction, but is not limited thereto.
If the pixel arrangement structure in the embodiment of the invention is applied to an OLED display device, the third sub-pixel 103 may be configured to emit blue light because the blue light material of the sub-pixel configured to emit blue light attenuates faster. For example, as shown in fig. 1 to 4, in one repeating unit 10, the third sub-pixel 103 is disposed opposite to the first sub-pixel 101 and the second sub-pixel 102, and the area of the third sub-pixel 103 is larger than the area of the first sub-pixel 101 and the area of the second sub-pixel 102. The aperture ratio of the third sub-pixel 103 is greater than the aperture ratios of the first sub-pixel 101 and the second sub-pixel 102, so that the service life of a display device adopting the pixel arrangement structure can be prolonged, and the display effect of the display device can be improved.
In one example, the shape of any one of the first subpixel 101, the second subpixel 102, and the third subpixel 103 may be a regular shape or an irregular shape. For example, the shape of the first sub-pixel 101, the second sub-pixel 102, and the third sub-pixel 103 may be a circle, an ellipse, a rectangle, a triangle, or other shapes, and is not limited herein.
